The platen stem 14 is shown mounted,v in the socket '15 and thisstructure is pivoted upon the pin 28. This pin 28 is carried in I thefoot or base plate 29 upon which the whole device stands. The socket 15has a rearwardly extending bracket 30 carrying an adjusting screw, andalso has a forwardly extending too 32. Infthe normal alined .position ofthe platens 13 and 10as shown in Fig. 1, the socket is carried by thepin 28 and the adjustment screw 31. When it is desired to insert orremove a box 16, then the stem 14 and the socket 15 are swung clockwiseabout the pin 28 until the toe 32 engages the base plate 29. In thisposition the platens 13 and 1.0 are disalined and the box with its oneend sealed may be removed and another which it is desired to seal put inits place. Thereupon the stem 14 is swung contra-clockwise to againaline the plunger 'so that the box flaps which have the socket andhaving a spherically rounded bearing surface at its end engaging thebottom of the platen to permitthe platen to rock in any direction, saidsocket having a substantially fiat beariug surface for engaging therounded extremity of said member.

2. In a box forming press, a platen having a socket on the bottomthereof, a platen supporting member loosely fitting in the socket andhaving a spherical rounded bearing surface atits end engaging the bottomof the platen to permit the platen to rock in any direction, said sockethavinga substantially flat bearing surface for engaging the roundedextremity of said member, and a set screw threaded in the socket and engging an opening in the side of the platen s pporting member.

3. A platen connection for box forming presses, comprising a slidablymounted spring pressed pin having a rounded bearing surface for tiltablysupporting the platen bearingsurface between the head. pf the\ pin andthe bottom ofthe platen tcij permi 1 said pin adapted through the agencyof said spring to take. the thrust ifrom said platenf. 7 i

5. In a press for forming paper boxes and the like, a platen having asocket formed on the bottom thereof-,a plateif s'uppmting stem having athreaded conneetionfor longitudinal adjustments, a shouldered bushingfitting in the platen supporting stem, means for preventing the bushing"from turning within the platen supporting stem. :1 headed pin sli'dablymounted in the bushing. a key for preventing the turning of the pin inthe bushing, a coil spring surrounding the pin and engaging the head ofthe pin and the bushing respectively, the head of the pin fittingwithin-the socketlof the platen and having-a spherically rounded bearingsurface to permit the platen-to rock in any direction, and a set screwthreaded in the socket and loosely engaging an opening in the head ofthe pin to prevent the platen turning on the pin.

6. In a device of, the character described the col'nbination with ilWYOplatens, means whereby said platens are. moved into and out ofparallelalined relation. means for the platen to rock iand a slidable support 1moving said platens relatively toward and I away from each otherwhen intheir alined condition, and a stem for supporting one of said platenshaving a rounded upper hearing surface and said platen having acooperating substantlally flat bearing surface to engage the said stem.

In testimonywhereof, I' -aflix my signature, in presence of twowitnesses.
